Performance Monitoring
Response time, packet loss and availability collected server-side from ManageEngine. Missing measurements stay empty — they are never counted as zero.

Response time trend
Mean latency per bucket, in milliseconds.

Nothing is plotted here because no value was collected — this is not a zero reading.
Packet loss trend
Mean loss percentage per bucket.

Collection notes
How this module treats data it did not receive.
- Only response time, packet loss and availability are collected. CPU and memory are out of scope.
- A metric with no measurement is stored empty and excluded from every average and chart line.
- Zero is only stored when ManageEngine actually reported zero.
- Stale after 15 min without a sample; older data is labelled STALE rather than presented as current.
- 0 device(s) reported measurements in the selected range.
